Codes & Ordinances, Comprehensive Plans, & Zoning

FDEP & WMDs:

TMDL/BMAP, MS4, ERP Programs

Avoidance (LID)

• Map natural infrastructure

• Preserve open spaces, natural areas, trees and native soils

• Retain natural hydrologic and topographic features in site plan

Minimization (LID)

• Limit and disconnect impervious surfaces

• Mimic and maximize predevelopment hydrologic processes

• Integrate practices that provide co-benefits and multifunctional areas

Mitigation (GSI)

• Implement runoff source control measures

• Employ natural processes to treat and retain stormwater

• Provide treatment and attenuation in multiple areas across the site

Provide minimum stormwater treatment “performance” criteria – no longer “technology based” or “presumptive”.

ERP Stormwater Rule Updates Overview

Increase overall treatment and removal of nutrients (TP and TN)

Ensures consistent application of net improvement performance standards.

Establish updated stormwater best management practices that more accurately reflect latest scientific information on their performance.

Strengthens requirements for operation and maintenance of stormwater systems.

Minimum Parking Requirements

• Commercial and residential codes

• Directly/indirectly increases impervious parking areas

• Seldomly used spaces

• Pervious parking

Use of Traffic Islands: Disconnect Impervious

Curb and gutter requirements indirectly prohibit swales.

Code Audit Tool

• Based on:

• WI Sea Grant Tool

• Center for Watershed Protection Tool

• Adapted to Florida’s Karst and Coastal Areas

• Partnership between UF IFAS. TNC Florida, and Eric Livingston

• Identify explicit & implicit restrictions or barriers to LID+GSI

Code Audit: Scoring Examples

M7. Is shared parking allowed for multiple businesses or sites with different peak usage times?

Tips

Purpose: Reduce number of onsite parking spaces

Facilities in close proximity to each other with different peak usage times, e.g., stores, restaurants, churches, and recreation areas, are good candidates to share parking. Physical access may be needed at multiple locations, and a legal agreement is necessary. Maintenance responsibilities must be addressed.

Code References

Sec. 407.18. - Parking reductions or increases.

Article 40 chapter 407 Sec. 407.68.Transit supportive area design standards. (2)Parking spaces may be pooled and utilized anywhere within the development.

Notes, Ideas and Strategies Score

Code does not specifically address "Peak usage times" but it does consider shared parking as a means of sufficient documentation for a decrease in off street parking spaces

Consider providing guidance for the documentation including this approach. 2

Code Audit Process:

Community Scoping Exercise

• Assess GSI in the community and local acceptance of GSI, identify local natural resources, identify water quality and stormwater challenges and solutions

• ID specific code sections or topics for the audit

Code Audit Spreadsheet Tool

• Adapt CAST to full or partial audit

• Work through questions, finding & referencing code locations

• Record comments and score questions

• Identify weak areas of code

After the Audit

• Prioritize code amendments for local needs

• Draft suggested code revisions (Part 2 in development)

• Evaluate and address financial concerns

• Develop LID+GSI capacity (e.g., construction, inspection & preventative maintenance knowledge & procedures)

Does code require a conservation and restoration strategy that identifies and protects natural areas, prioritizing those providing stormwater management functions?

10 Steps to Effective Incentives Other

Incentives: Objectives & Audience

1. Determine Objectives – Set goals and measures

Here we want to improve stormwater management and water quality through effective implementation of GSI + LID in new development and redevelopment projects; and wherever else possible

2. Analyze the Audience – Who can impact the objectives?

• Developers; Engineers; Home Builders; Property Owners; Public

• Regulators; Enforcers; Officials; Public

Incentives: Fact Finding

3. Fact Finding & Audience Involvement (ENRAC, etc.)

Here: What do we do to improve stormwater management and water quality through effective implementation of GSI + LID in new projects; and where ever else possible

Recommendation:

• Ordinance requirements for new development and redevelopment projects, e.g. residential subdivisions; large multi-family and nonresidential projects.

• Incentives for existing development.

4. Create Rules Structure and Develop Budget – rules of the program; fixed and variable costs

Here: Available resources to administer the program or need for additional resources; available processes to administer the program or need for new procedures; program management.

5. Select Awards – appeal; budget; match

What incentives will the Audience value? bonus density (caps), reduced dimensional regulations, fee waivers; property tax abatements, priority permit processing; compliance grants; etc.

Incentives: Outreach, Tracking, & Awards

6. Communicate the Program – Appropriate media to expand audience

Outreach to the public – possible parallel with the educational efforts we use to promote the local NFIP regulations to capture credits for the Community Rating System

7. Operations – Track results with regular progress updates

Again, a function of budget, capacity, and resources

8. Fulfill the Awards – more immediate = better!

9. Evaluate & Measure – Objective accomplished? Any outside factors?

This is the back end of steps 4 (Rules) and 7 (Tracking). Are we making progress toward our objective(s)?

10. Celebrate Success! – Reward achievers; communicate results; annual dinner; awards; public recognition.

This is probably the most public-facing aspect and provides additional incentives to participate whether through regulatory (LDRs) or voluntary compliance.
